Stability enhancement of coal measures strata with water-based chemical agents
Tóm tắt
This paper summarizes a contract report of work undertaken on behalf of the Department of Energy, Mines and Resources to ascertain the effectiveness of surface applied chemicals as a swelling retardant for use in underground coal mines. It addresses the mineralogical, chemical and mechanical aspects of the swelling clay problem. The experience of the use of swelling retarders in the oil well drilling industry is reviewed and the various types of stabilizing chemicals discussed. Finally, potential applications of the technology in coal mining are discussed with mention of the toxicity of the chemical agents and their relative costs.
